Short summary

The oxidative potential (OP) of ambient particulate matter (PM) has recently gained attention as an alternative metric for assessing the ambient PM toxicity. However, a major constraint in measuring the OP is its labor-intensive protocol. Here, we developed a new online instrument by coupling a mist chamber to an automated analytical system which can measure the real-time OP of ambient PM. We also report for the first time, the hourly averaged diurnal profile of ambient PM OP at an urban site.
